I already own a chunk of aerogel (aka "frozen smoke"), which I pull from its little plastic container every couple of years to marvel at. I keep it in a bedside table drawer that's become my de facto cabinet of curiosities. My next addition to the cabinet is a chunk of gallium, because it's a metal that liquifies at 85.59°F so it will melt in your hand.

Now that the world is starting to re-emerge from its self-imposed COVID-19 quarantine, we’re all going to have to start making some adjustments to both short-term and long-term changes. And the questions… Should customers be hounded out of a store if they aren’t wearing a face mask? Are crocheted face masks safe or not? And […]
Maybe you had a piano teacher as a kid that drove you off the instrument forever. Or maybe you always wished for some serious training, but never found the time. Whether you have dreams of tossing off a Beethoven or Chopin piece at the drop of a hat or you have visions of being the […]
